Front

What is the total surface area of a prism?

Back

The total surface area of a prism is the sum of the areas of all its faces, including the two bases.

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = bh + l1h + l2h + l3h, where b = base area, l1, l2, l3 = lengths of the sides of the triangle, h = height of the prism.

Front

What is the total surface area of a square pyramid?

Back

Surface Area = base area + 1/2 × perimeter of base × slant height.

Front

What is the difference between a prism and a pyramid?

Back

A prism has two parallel bases and rectangular sides, while a pyramid has one base and triangular sides that meet at a point.

Front

How do you find the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What is the total surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r = radius and h = height.

Front

What is a triangular pyramid?

Back

A triangular pyramid is a three-dimensional shape with a triangular base and three triangular faces that meet at a point.
